I don't see why you can't use that block over... The pictures don't show horrible scoring and if you bore and hone to 100mm you should be just fine. Also I'm sure you can salvage at least one of the sets of rods and you can get a brand new crank for $300. If you go this route just make sure the bore and hone is done with a torque plate and matched to the pistons you buy. Otherwise you will have piston slap.
If you do get a new block already built I recommend you find a block with new rods as well as pistons. The stock rods are weak sauce and anything past 400whp is questionable.
